TOBOGGAN.

SPECIFICATION forming part of Letters Patent No. 367,268, dated July 26, 1887.

Application filed March 10, 1887. Serial No. 230,431. (No model.)

To all whom, it may concern:

Be it, known that I, FENELON B. BROOK, a citizen of the United States, residing at \Vashington, in the District of Columbia, have in- Vented certain new and usefullmprovementsin Toboggaus; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable'others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,which form a part of this specification.

My invention relates to toboggans or sleds,

the object of which is to construct such a vehicle so thatit may be used either as a toboggan and lie substantially flat upon the surface of the snow or ice, or upon runners, such as are commonly used upon sleds, or, in other words,

go my object is to providea toboggan which may be converted into a sled having runners.

For the above purposes my invention consists of a toboggan provided with a piece or rail,which may be moved under the body thereof for use as a runner, or may be moved out of the way that the body may lieupon the snoworice. Myimprovementconsists inother details of construction and combination, all of which will be first fully described, and then re- 0 cited in the claims.

Figure 1 represents a plan of a toboggan,to which [have applied my improvements. Fig. 2 represents a side elevation of the same. Fig. 8 represents a detail transverse section on an 3 5 enlarged scale, showing the rail or runner swung upwardly, sothat the toboggau may lie flat upon the surface; and Fig. 4 represents a similar transverse section, showing the runner in full lines swung under the bottom of the toboggan, and in dotted lines swung above the bottom, and also in dotted lines showing the position of a permanent rail adjacent to the runner. Fig. 5 is a detail plan taken through the line :0 w of Fig. 3. Fig. 6 is a detail par- 5 tial section and-elevation of a modification of my invention.

The toboggan shown in the drawings is composed of the usual series of longitudinal slats, 1,united by a series of transverse cross-bars,2.

It is bowed or doubled upon itself at 3,to form the front or hood of the toboggan,in the usual manner.

' 4 represents a combined rail and runner mounted upon a series of posts, 5, which are hinged, so that this rail 4 may be either-swung upward, as shown in full lines, Fig. 2, and in Fig. 3, where it serves as ahand rail or guide, or swung downward, as shown in dotted lines, Fig. 2, and in Fig. 4, where it serves as a sledrunner. The posts 5 are preferably placed at the ends of each cross-bar 2. I

6 are boxes or'castings on the bars 2, in which the posts or standards 5 are hinged and locked. The boxes 6 are composed of parallel vertical sides 7 and a horizontal flange formed in one 6 piece with the sides 7. The ends of Crossbars 2 are slotted to receive the boxes.

8 are the bolts upon which the posts 5 are pivoted. They pass through the bar 2 and the side Walls, 7 ,of boxes 6,and are preferably provided with a nut, by means of which the ten sion of the posts may be regulated.

9 9 are two holes, arranged at either side of the bolt 8 in the posts 5. These holes alternately register with similar holes made through 7 5 both sides 7 of the box 6, in the upper part thereof.

10 is a pin,of which there is one for each box 6, which is adapted to pass through the holes 9 9' and those in the walls 7, for the purpose of locking the combined rail and runner 4 in either one ofits two positions. Fig. 3 shows the pin 1.0 passed through the hole 9, whereby the rail 4 is locked in position for use as a hand rail or guard, and Fig. 4 shows the pin- 10 8 passed through the hole 9' of post 5, whereby the rail is locked in position as a runner for a sled.

' 12 are screws or bolts for securing the flange llto a bar, 2, and 13 is a chain or cord to pre- 9o vent the pin 10 becoming misplaced or lost.

It will be noticed that the forward ends of the rails or runners 4 are curved, as shown in Fig.

2, so that when they are used as runners they will form practically a continuation of the bowed front 3.

Instead of making the usual hand-rail of the toboggan hinged, so that it may also be used as a runner, I may arrange the runner to swing up underneath, over, or alongside the usual roe permanent handrail, as will be hereinafter more fully indicated.

Instead of the swinging posts or standards, Inlay dispense with these and make the hinged runner comprise the outer horizontal portions or slats 1 of the toboggan itself and hinged to the body, so that they may swing down and be locked in place as runners. Such a con struction is shown in Fig. 6.

Other methods of locking the hinged runner in either position will suggest themselves.

In the modification shown in Fig. 6 the outside slat, 1, is preferably made thicker, as

shown, and hinged to the toboggan by the hinge 19. \Vhen swung down into the position shown in dotted lines, its outeredge forms the runner of the toboggan; but when swung into a horizontal position it forms part of the toboggan-bed. 4 is a permanent rail on slat or runner 1, and 5' posts or standards.

15 is a bolt for locking the runner 1 in a horizontal or perpendicular position. 14 are ways in which the bolt works. 16 is a projection or keeper, rigidly secured to theinner side of runner 1. It has two holes, 17 and 18, at right angles to each other, adapted to receive the bolt 15 when the runner 1 is in either position.

\Vhen the runner 1 is in a horizontal position, the bolt 15 is adapted to be pushed into the hole 18, as shown in full lines, and lock the runner. Vhen the runner is in a vertical position, or at right angles to the horizontal position, the bolt 15 may be pushed through the hole 17 and lock the runner, as shown in dotted lines.

In Fig. 4 I have shown in dotted lines the position of a permanent rail, 20, in connection with the adjustable runner 4. The standards 21 of the rail 20 may be curved, as shown, in order to admit the runner 4 beneath it, or the permanent rail and standard may be located alongside the swinging runner on the inner side.

I claim- 1. A convertible toboggan and sled provided with runners adapted to be swung on a level with or above the bottom of the toboggan and under the bottom for use as runners, substantially as shown and stated..

2. A toboggan or sled, a combined rail and runner, and nieans,substantially as described, for shifting said rail or runneigwhereby it may be used as a rail or guard and a runner.

3. A toboggan provided with an adjustable runner adapted to leave the bottom of the toboggan free and unobstructed, and also to projcet beneath the bottom.

4. A toboggan provided with an adjustable runner adapted to project beneath the bottom and to be withdrawn therefrom, and aloek for securing the runner in one or both positions.

5. A toboggan provided with a series of hinged posts and a rail or runner secured to said posts or standards, whereby the rail or runner may be swung above or below the t0- boggan.

6. A toboggan provided with a series of hinged posts or standards, runners secured to said posts, and a lock whereby the runners may be locked above or below the toboggan.-

7. In a toboggan, a hinged post provided with a hole at either side of the pivotal point, a box or casting having a hole or holes, and a pin adapted to pass through the holes in the box and through either one of theholesin the post, all in combination, as stated.

8. A combined hinged rail and runner having its forward end curved, substantially as shown and stated.

In testimony whereof I affix my signature in presence of two witnesses.
